Verified step by step guidance
1
Understand the process of RNA splicing: RNA splicing is a crucial step in the maturation of pre-mRNA into mature mRNA. It involves the removal of non-coding sequences called introns and the joining of coding sequences called exons.
Learn about the location of RNA splicing: In eukaryotic cells, RNA splicing occurs in the nucleus, not the cytoplasm. This is because the pre-mRNA is transcribed in the nucleus and undergoes processing there before being exported to the cytoplasm.
Explore the role of spliceosomes: Spliceosomes are complex molecular machines composed of proteins and RNA that facilitate the splicing process. They recognize the intron-exon boundaries and catalyze the removal of introns.
Understand alternative splicing: Alternative splicing allows a single gene to produce multiple protein variants by varying the combination of exons included in the final mRNA. This increases the diversity of proteins that can be generated from a single gene.
Identify the false statement: Given the information above, the statement 'Splicing occurs in the cytoplasm of eukaryotic cells' is false because splicing occurs in the nucleus.
